# Symbiosis Developer Tools

## Introduction

Symbiosis Developer Tools include the **Symbiosis JS SDK** and **Symbiosis API**, designed to simplify integration with the Symbiosis protocol and provide developers with robust, scalable solutions for cross-chain and on-chain operations.

* **Symbiosis Core Smart Contracts:** Open source and available on [Github](https://github.com/symbiosis-finance/core-contracts).
* **Security Audits:** Reports available here: [security-audits](https://docs.symbiosis.finance/main-concepts/security-audits "mention").

## Features Available via the API and SDK

Both the Symbiosis API and JS SDK provide access to the following cross-chain and on-chain operations:

1. **Swaps:**
   1. **Cross-chain swaps** – Swap *any token* across supported blockchain networks.\
      \&#xNAN;*In short:* [symbiosis-cross-chain-swaps](https://docs.symbiosis.finance/main-concepts/symbiosis-cross-chain-swaps "mention")
   2. **On-chain swaps** – Swap *any token pair* on a supported network.
2. **Interchain communication** – Transfer tokens to third-party protocols.\
   \&#xNAN;*In short:* [symbiosis-as-interchain-communication-protocol](https://docs.symbiosis.finance/main-concepts/symbiosis-as-interchain-communication-protocol "mention")
3. **Cross-chain zapping** – Zap any token into a Symbiosis-managed liquidity pool.\
   \&#xNAN;*In short:* [cross-chain-zaps](https://docs.symbiosis.finance/main-concepts/cross-chain-zaps "mention")
4. **Bridging** – Mint or burn tokens to transfer assets across chains.\
   \&#xNAN;*In short:* [synthesizing-process](https://docs.symbiosis.finance/crosschain-liquidity-engine/synthesizing-process "mention")
5. **Cross-chain operation status tracking** – Retrieve real-time transaction status updates.
6. **Emergency handling:**

   1. Retrieve a list of stuck cross-chain operations.
   2. Generate calldata for reverting transactions.
